Sound isolation structure

Abstract

A sound isolation structure includes an array of resonators. At least one of the resonators forming the array of resonators may include a housing having a cavity, an opening to the cavity, and a neck portion extending into the cavity from the opening of the housing. The cavity may be in the form of an air channel having an open end connected to the opening and a terminal end.

         8 . The sound isolation structure of  claim 1 , wherein the housing further comprises a top plate having the opening, the top plate having a side opposite of the cavity that is substantially flat. 
     
     
         9 . The sound isolation structure of  claim 1 , wherein the array of resonators is a two-dimensional array of resonators. 
     
     
         10 . A resonator for isolating sound, the resonator comprising:
 a housing having an opening;   an air channel disposed within the housing, the air channel having an open end connected to an opening and a terminal end terminating within the housing; and   a neck portion extending into the air channel from the opening.   
     
     
         11 . The resonator of  claim 10 , wherein the air channel is a spiral air channel.
